Abstract:The study on spatio-temporal variation of soil heavy metals is of important significance in sustainable utilization of the soil and protection of the eco-environment.Soil samples were collected from vegetable fields (0~20 cm) in the preiurban areas of Hangzhou City,43 in 2001 and 74 in 2005,determined for total Pb and total Cu,and analyzed with the Morans Ⅰ,Geostatistics and the Fractal methods for their spatio-temporal variation of soil heavy metals Results show that themean content of soil Pb and Cu in creased form 38.73 mg kg-1 and 31.20 mg kg-1 in 2001 to 46.14 mg kg-1 and 36.56 mg kg-1 in 2005,respectively,demonstrating a significant increase The autocorrelated distance of soil Pb and Cu at the 0.05 significance level decreased from 3 500 m to 2 700 m and from 3 300 m to 2 800 m,respectively,showing a decreasing trend in spatial distribution of soil Pb and Cu from west to east across the study area.The accumulation of soil heavy metals might be attributed to intensified human activities.
